Be it known that I, JOHN SUBZYOKI, a citizen of the United States, residin at Reeds'burg, in the county of. Sauk and tate of Wisconsin, have invented new. and useful Improvements in Street-Sweepers, of which the following is a specification.

The present invention relates to street sweepers or cleaners.

The primary object is to provide novel, simple and practical mechanism for collecting the sweepings into piles in the gutter, so that they may be more readily removed, and the services of workmen to manually form the piles, can thus be eliminated.

A further object is to rovide a structure of this character'that will conform to the unevenness of the surface over which the same travels, and also to provide-collecting means that will'pro rly traverse curves or inequalities, due to t e curbing and the like. An embodiment of the'invention is illustrated in the accompanying drawings, wherein Figure 1 is a plan view of .one type of machine, showing t e vention applie thereto. Fig. 2 is a side elevation of the same. Fig. 3 is a detail sectional View on the line 3-3 of Fig. 1. F i 4 is a detail plan view of the collector an its supporting means. Fig. 5 is a lonitudinal sectiona view therethrough. Fig. 5 is a detail view, showing one form of treadle for elevating the col ector, and Fig. 7 is a diagrammatic view, illustratin how the device will conform to curves, an still operate properly.

Similar reference numerals designate corresponding parts inall the figures of the drawings.

The sweeper may be of any desired or well known type, and in the present embodiment, comprises a suitable main frame 9, supported on wheels 10, and carrying an inclined rotary brush 11, driven through suitable gearing, designated generally y the reference numeral 12. The drivers seat is illustrated at 13. So far as thus disclosed, this structure is well known.

Mounted atthe dischar e end of the brush, is a bracket 14, this racket, in the present embodiment, being shown as pivoted by a bolt 16 to the bearing member 16 of the brush, which bearing member is con- Specification of Letters Patent.

nected to an arm 17 extending from the main frame. It will of course be understood that the bracket can be su orted by any desired means. It is norma l3 held in fixedrelation by a bolt 17 passing through a curved slot 18, the radius of which is the centerof the ivot bolt 15. By means of the nut on the olt 17, the said bracket can be held against movement in any desired adjusted position. A laterally or horizontally swinging arm 18 is pivoted to the rear end of the bracket, and as shown more particularly in Fig. 5 this arm 18 has its rear end bifurcated as illustrated at 19 to receive a vertically swinging arm 20, pivoted in the bifurcation by the bolt 21. The front of the arm has an arc-shaped guide 22, and its rear end, which extends beyond the arm 18, has an upward projecting portion 23 and :1

depending pro ectin portion 24. Pivotally connected to tie depending portion 24 by a bolt 25, is a bail 26, to the ends of (pivotally connected, as shown at e arms of a substantially U- shaped collector or scraper 28, the arms of .which extend forwardly in rear of the dischar 0 end of the brush, one arm slightly over zipping the point or line of discharge, as wil e clear by reference to Fig. 1. The

other arm is provided at its front end with a horizontally disposed roller 29 that is arranged to operate against the curb of the street being swept, as will be clear by reference to Figs. 1 and 5.

In order to maintain the collector 28 flat against the surface over which it travels, the following mechanism is preferably employed: An ear 30 is secured to the rear central portion of the collector and extends slightly above the same, being rearwardly inclined. To this ear is bolted a stem 31, to the upper end of which is pivoted a rod 32. This rod slidably passes through another ear 33, mounted on one side of the rearwardly extending arm 20. A coiled spring 34, surrounding the rod 32, bears at one end against the ear 33, and at its other end against a collar 35, located at the joint between the rod and stem. This s ring, it

38, fastened in an. outstandingfiner' that is carried by theadj'us table brac et 14.,

The action of this spring is to I's'wing the arm 18, and consequentlythe collect/ontoward the curb, as will be obvious.

In order to raisethe collector 28 for. the

purpose of discharging the material in piles, orto hold the collector out of action when thesweeping mechanism ,is inactive -a treadle or foot-piece is located in convenient relation to the foot of the driver, and in the present embodiment, such afoot-piece or treadle is'shown at 40, being carried by a crank arm 41 that forms a part of a rock shaft 42 journaled on the platform of the machine. .Another crank arm 43, carried by saidrock shaft, is connected to the up-- standing projection .23 of the arm 20 by, a link 44. A spring 45, in the present embodiment shown as connected to the arm 43,

serves to hold said arm 43 in its rearmost position. in rorden. that the collector may properly operate but. a: suitable dog associated with the treadle is employed to engage a rack, bar 45, in order that the arm 43 and con uently the collector may be held elevated-.if'desired. It will, of course be understood that the particular type 0% dog 44and the arrangement of the spring 45 ma bev changed, as desired.

Wit thisstructure, it will be clear that as the machine see, the sweepings will be delivered the driver has only to ress upon the treadle 40 to elevate the col ector, and thus -discharge the collected sweepings in piles. The said collector because of its mounting is permitted to have play in various directions, and yet is yieldmgly maintained in properly operative position, at all times. Thus, t e inequalities and roughness are accommodated, and should the collector strike an immovable obstruction, it will yield and passdthe same without being materially inure From the foregoing, it is thought that the construction, operation and many advantages of the hereindescribed invention will be apparent to those skilled in the art without further description, and it will understood that various changes in the size, shape, proportion and minor details of construction, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus fully described m tion, what I claim as new, and secure by Letters Patent, is:-
